Compressed sensing (CS) algorithm has been brought into MRI. CS realizes iterative reconstruction of images from incoherently under-sampled data, which leads to shorter acquisition time. A 3D T1-weighted fast spin echo (T1-FSE) scan has been often used for plaque imaging. We compared visualization of carotid plaque and internal carotid artery (ICA) between 3D T1-FSE imaging with SPACE and with a prototype CS SPACE. In the result, CS-T1-SPACE revealed an equivalent visualization compared with T1-SPACE in evaluation of carotid plaque and ICA. CS-T1-SPACE would be useful for the visualization of carotid plaque and ICA.
